M16 MODEM
M-16 is designed for transmission of delta-coded speech on leased duplex telephone lines, based on analog carrier systems. Modem implements modified QAM-64 modulation and advanced equalizers, all designed to assure best quality of connection in analog telephony networks. The design has been based fully on digital signal processing. M-16 capabilities: • Implements modified V.33 ITU standard • Two digital interfaces: V.24 (with optionally error correction) and S1I (for CVSD) • Analog service voice / data channel • Device diagnostics: control loops and BER measurement • Working temperature:-30° ÷ +60°C • Power supply: 27DC (22÷30V) • Remote mamagement using Q2 interface |
